【正文】 武漢科技大學(xué)本科畢業(yè)設(shè)計(jì) 摘 要 近年隨著鋼鐵，汽車，家電行業(yè)的發(fā)展，對(duì)鋼板要求越來越高。由于種種原因軋后鋼材必須經(jīng)過矯正，才能消除制品的彎曲和扭擰，波浪彎和瓢曲等缺陷以達(dá)到國家規(guī)定的質(zhì)量標(biāo)準(zhǔn)。所以矯正機(jī)在軋鋼機(jī)械中有著舉足輕重的地位。由于施加鋼材反向彎曲或拉伸的方式不同及結(jié)構(gòu)上的不同而有不同類型的矯直機(jī)，所以矯直鋼材所需的矯直機(jī)的種類有很多種，驅(qū)動(dòng)矯直機(jī)的減速分配箱也有各種各樣的傳動(dòng)方式。因此，需根據(jù)矯直機(jī)的要求設(shè)計(jì)專門的傳動(dòng)分配箱。本文的設(shè)計(jì)方案是：由一個(gè)電動(dòng)機(jī)驅(qū)動(dòng)的，經(jīng)過一級(jí)減速的，通過五個(gè)小齒輪進(jìn)行分配的整體減速分配箱。由于圓柱齒輪減速機(jī)的制造和安裝較為簡(jiǎn)單，因此在矯直機(jī)主傳動(dòng)系統(tǒng)中得到廣泛的應(yīng)用。將該矯直機(jī)的減速分配箱，制造成聯(lián)合減速機(jī)。因?yàn)閷p速機(jī)和齒輪座組成一個(gè)整體，可減少傳動(dòng)件，且結(jié)構(gòu)緊湊，能減少機(jī)列總長(zhǎng)度，節(jié)省精整車間的空間。在整個(gè)設(shè)計(jì)中，本文對(duì)減速分配箱箱體內(nèi)的各零件做了仔細(xì)的設(shè)計(jì)計(jì)算和校核，通過對(duì)箱體內(nèi)各零件的合理的布置以及各部分的完善，最終設(shè)計(jì)除了滿足要求的矯直機(jī)的主傳動(dòng)系統(tǒng)。 本文設(shè)計(jì)的主參數(shù)如下：選擇電機(jī)為：Y系列，其轉(zhuǎn)速為nm=960r/min。減速機(jī)為一級(jí)減速，其傳動(dòng)比：i=3分配箱經(jīng)一級(jí)分配。分配齒輪齒數(shù)為Z=21關(guān)鍵詞：矯直機(jī)；矯直機(jī)主傳動(dòng)機(jī)構(gòu)；減速分配箱；減速機(jī)；機(jī)架 Abstract In recent years, with the iron and steel, automobiles, household appliances industry, increasing demands on the plate. For various reasons must be corrected after rolling of steel to eliminate bending and twisting products, wave bending and buckling and other defects in order to meet the national quality standards. So straightening machine in the steel rolling machine has a pivotal position. Since the reverse bending or stretching of steel applied in different ways and different structures have different types of straightening machine, so the required straightening steel straightening machine There are many types, the drive gear straightening machine distribution box there are a variety of transmission mode. Therefore, the request must be in accordance leveler drive designed specifically assigned box. This design is: driven by a motor through a speed reduction through the allocation of five overall pinion gear distribution boxes. Because the manufacture of cylindrical gear reducer and installation is simple, so straightening the main drive system is widely used. Slowdown in the straightening machine distribution box, manufactured jointly reducer. Because of the speed reducer and gear housing to form a whole, can reduce the transmission parts, and pact machine can reduce the total length of the column and save the space between fine vehicle. In the whole design, the paper distribution boxes cabinets gear made of various parts of the design calculations and check carefully through the various parts of the cabinets of the layout as well as a reasonable part of the perfect addition to meeting the requirements of the final design straightener The main drive system.In this paper the main design parameters are as follows:Select motor: Y series, power of of Y132M26type motor, the speed is nm = 960r/min.Reducer is a reducer, the gear ratio: i = 3Distribution by a distribution box.
